N2 - This paper presents the design and preliminary experimental verification of a multigrasp myoelectric controller. The controller enables the direct and proportional control of a multigrasp transradial prosthesis through a set of nine postures using two surface EMG electrodes. Five healthy subjects utilized the multigrasp controller to manipulate a virtual prosthesis to experimentally quantify the performance of the controller in terms of real time performance metrics. For comparison, the performance of the native hand was also characterized using a dataglove. The average overall transition times for the multigrasp myoelectric controller and the native hand with the dataglove were found to be 1.49 and 0.81 seconds, respectively. The transition rates for both were found to be the same (99.2%).

This type of prosthesis is used for above-elbow (transhumeral) amputations.

This type of prosthesis is used for below-elbow (transradial) amputations. The transradial prosthesis typically includes , wrist unit, elbow unit, socket and harness. The selection of these components is based on a patient’s functional goals and capabilities.

A transhumeral prosthesis is an artificial limb that replaces an arm missing above the elbow.

A systematic search of the literature was conducted in July 2013 using the following databases: PubMed (1947–present), CINAHL (1981–present), RECAL Legacy (1900–2007), Cochrane Database of Systematic Reviews (1992–present), Cochrane Clinical Trials Registry (1992–present), EMBASE (1974–present), PMC-NIH Research Publication Database (2000–present), Web of Science (1900–present), and Google Scholar (early 1900–present). The databases were searched using broad key words related to upper-limb prostheses. The key words were combined into search statements. The following key words were used to search the databases: myoelectric, body-powered, hybrid, externally powered, transradial, transhumeral, upper limb, prosthesis, artificial limbs, voluntary opening, and voluntary closing. A detailed description of model statements are described in Hafner [20]. EndNote bibliographic software, (version X6, Thomson Reuters; Philadelphia, Pennsylvania) was utilized to build the reference library. Additional articles extracted from authors' knowledge of literature in the field, from manually reviewing references of articles identified in the electronic search, and from standard literature email updates were added.

Specific characteristics of the included publications are shown in . The reviewed studies were classified into 9 of the 15 potential study designs described by the AAOP study design classification scale [20]. The distribution of the studies by study design is shown in . Sample sizes ranged from 1 to a maximum of 1,216 adults from one study [27] that surveyed individuals using various types of prostheses. The median subject size was 12 (including case studies). The average age of participants of the reviewed studies that reported subject age was 43.3 yr. Outcome measures reported in the reviewed publications included motion analysis, including range of motion (ROM); joint angles during ADLs; kinematics and compensatory motion; reaching/pointing velocity and accuracy; Box and Blocks (and modified); pinch forces; rejection rates; nine hole peg test; the Southampton Hand Assessment Procedure (SHAP); and surveys that included the Trinity Amputation and Prosthesis Experience Scales, the Orthotics and Prosthetics Users Survey, and custom surveys. The majority of the studies (21/31) was declared unfunded or did not specify funding.
